Within the superfield approach, we discuss the three-dimensional supersymmetric (SUSY) pseudo-QED. We prove that it is all-loop renormalizable. We demonstrate that the SUSY pseudo-QED action can be generated as a quantum correction from the coupling

Recently, in the literature, it was shown that the logarithmic renormalization of the Fermi velocity in a plane graphene sheet (which, in turn, is related to the Coulombian static potential associated to electrons in the sheet) is inhibited by the pr

We investigate the renormalization of the Fermi velocity in a plane graphene sheet in the presence of a parallel conducting plate. We use the pseudo-quantum electrodynamics to describe the Coulombian interaction between the electrons, but taking into

Quantum electrodynamics (QED) of electrons confined in a plane and that yet can undergo interactions mediated by an unconstrained photon has been described by the so-called pseudo-QED (PQED), the (2+1)-dimensional version of the equivalent dimensiona

We derive an effective two-dimensional low-energy theory for thin superconducting films coupled to a three-dimensional fluctuating electromagnetic field. Using this theory we discuss plasma oscillations, interactions between charges and vortices and

We use pseudo-quantum electrodynamics in order to describe the full electromagnetic interaction of the p electrons in graphene in a consistent 2D formulation. We first consider the effect of this interaction in the vacuum polarization tensor or, equi

We discuss several aspects of a generalization of the Chern-Simons action containing the pseudodifferential operator −□, which we shall call pseudo-Chern-Simons (PCS). First, we derive the PCS from the bosonization of free massive Dirac particles

We describe the dynamical mass generation in pseudoquantum electrodynamics (PQED) coupled to the Gross-Neveu (GN) interaction, in (2+1) dimensions, at both zero and finite temperatures. We start with a gapless model and show that, under particular co

In the present paper, we investigate the influence of a grounded perfectly conducting surface on the photon self-energy of a $2+1\mathrm{D}$ system of massless Dirac fermions, whose electron interaction is described by pseudoquantum electrodynamics.
